MULTIGRAPH TYPE.

Application filed May 31,

This invention relates to improvements in type cast in slug form similar to the ordinary line of t pe for use inthat form of printing machine wherein the bed plate is transversely slot-ted to receive individual type and has lips overhanging such slots to enter grooves formed in opposite sides of such type when the type are inserted into the slots of the bed plate through one end of the latter. u

The principal object of this invention is to produce an integral lineof type or slug wh ch may be slid into a slot in the bed plate of such a machine, thereby obviating the usual labor of setting up individual type.

A further object is to produce a slug or line of type which may be formed in a ma, chine for producing lines of type and later be broken from the main body of the slug.

A stillifurther object is to produce a device of this character wherein the form of the line of type is such "as to automatically center and hold itselfinjthe bedplate.

A still further object is to provide slugs formed from a minimumamount of metal and which will nest during shipment thereby taking up a minimum amount of space.

Other objects andadvantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure I is a perspective view of a type slug and body portion, as the same appears when cast,

Figure II is an end view, on an enlarged scale, of one of the type slugs shown in Figure I Fi ure III is a view similar to Figure II, showing the body portion broken away from the type slug,

Figure IV is a view similar to Figure II of a slug and body portion of the form produced when casting type of small size,

Fi re V illustrates the manner of using the orm of slugs of Figure IV in the bed plate of a printing machine of the character referred to above and showing the bed plate in cross section,

Figure VI illustrates the manner of using slugs of the form shown in Figure II of the bed plate of such a machine, which bed plate is shown in cross-section, and

Figure VII is an end elevation of a num 1927. Serial a. 195,355.

ber of the slugs packed in lapped relation thereby taking up buthalf the amount of shipplng room which would be otherwise necessary. V

In the employment of printing of the character referred to itis necessary to set upth e type from which the printing is to be done, which setting up operation is a tedious one due tothe small size of the individual type which'are hard to handle and thereforeeasily dropped. 4 v i I have therefore perfected a type slug wherein the individual type are castin a line upon a slug body, after which the whole is ejected from thecasting machine and the head or line of type is broken away from the body of the slug and then employed for printing purposes.

I am aware of the fact that various attempts have been made to accomplish this object, but due to the fact that square shoulders were formed upon the slugs these lines of type could not be readily ejected from the molds in which they were produced without employing a complicated mechanism for opening the-molds, which mechanism is impractical for use with the standard" forms ofmachines for casting lines of type.

By forming a type slug having cam surfaces, I have perfected a type slug which may be readily ejected from the type forming machine.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the type face which is cast upon the head 6 of the slug. Depending from the head 6 is a web portion 7, which web portion is flared so as to form cam surfaces 8 and 9 adjacent the rear end of the line of type slug.

The base 9 of the slug is connected to the remainder ofthe slug by a restricted portion 11, in such a manner that cam sur faces 12 and 13 are formed upon the forward end of the base;

In the construction shown in Figure IV, it will be noted that the. head 6 is narrower than the portion on which the cam surfaces 8 and 9 are formed. This permits the construction of small point type and it will also be noted that in this modified form the cam surfaces 8 and 9 are connected directly to the head 6, the purpose of which will be later seen.

In use that portion of the slug which cari ries the type face is broken away from the slug body as indicated at a, in Figure III, after which the type bearing slug portion may be slid into the bed plate of the printing machine, which bed plate is indicated at let of Figures V and VI.

The cam surfaces 8 and 9 will bear against the under-surface of a slot in the bed plate and thus automatically position the type bearing slug centrally with respect to the slot, and at the same time will prevent the slug from moving away from the face of the bed plate. Heretofore, it has been impossible to employ small point typeor slugs in the slotted bed plate of a printing machine but by forming the slug as indicated in Figure IV, a bed plate construction as'indicated in Figure V may be made which will permit type slugs of small point to be used.

It will be further noted that the base of the slug is cut away as shown in Figures I, II, III andIV so as to form a flat shoulder 15 and a cam surface 16. Thecam surface 16 has the same pitch as the cam surfaces 8 and 12,that is to say, it is parallel with the latter surfaces, the result being, that, during the ejecting operation, thecam surfaces will ride over the inclined surfaces of the two members of the mold in which the slug is formed, thus evenly lifting the cap member of such mold from the back to the front of the latter.

The cutting away of the 'base of the slug as just indicated also permits the shipping of the slugs in a nested condition, as shown in Figure VII which takes up much less space in packing, and further when type slugs are packed in this manner, greater rigidity is given to the package and therefore there is less liability of mutilation of the slugs.

It will 'thus be seen that I have provided a type slug having peculiar characteristics which will perform all of the objects above set forth.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same, and that various changes relative to the shape, material, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim V A type slug for use in a printing machine having a bed plate provided with transverse type-receiving slots, comprising a type hearing member, a web portion having its inner extremity flared outwardly and rearwarclly to form cam surfaces, a connecting body portion adapted to be removed therefrom, said body portion having cam surfaces formed parallel to said first mentioned cam surfaces, and being cut away substantially half of "its width to form a'shoulder substantially parallel with the head of the type bearing member and a-cam surfaceparallel with one of said first mentioned cam surfaces.

In testimony whereof I ailix my signature.
